is its composition? At what pressure does thelast bubble of vapor disappear, and what was itscomposition? Data: The vapor pressures of the componentsare given byB. \log _{10} P_{\mathrm{i}}^{\mathrm{vap}}=A_{\mathrm{i}}-\frac{B_{\mathrm{i}}}{T} for pressure

in bar and T in K, whereA1 = 4.125, B = 1500, A2 = 5.000, andB12 = 1750.%3D
